Application led June 7, 1918.

T all ywhom it may concern.'

Be 1t known that we, AUGUST R. LUSCHKA and JosErH FOLK, citizens of theUnited I States7 residing at Laporte, in the county of Laporte and Stateof Indiana, have invented certain new and useful Improvements inSlicing-Machines, of which the following is a specification.

This invention has for its object the vprovision of a machine of theclass named which shall be of improved construction and operation.

The invention is exemplified in the combinat-ion and arrangement ofparts shown in the accompanying drawings and described in the followingspecification, and it is more particularly pointed out in the appendedclaims.

In the drawings- Figure 1 is a side'elevation of a slicing machineembodying one form of the present invention.

Fig. 2 is a bottom plan view of the machineshown in Fig. 1.

Fig. 3 is a side elevation of the base frame of the machine with theguard for the -drive belt removed.

Fig. 4 is a view similar to Fig. 5 with the gear casing and cover forthe motor removed, and with parts in section'.

Fig. 5 is a vertical section substantially on line 5 5 of Fig. 2; andFig. 6 is a horizontal section on line 6 6 of Fig. 1.

In Figql of the drawings, the base frame 10 of the slicing machine isshown as arranged upon a pedestal 11, and provided onl its upper surfacewith a pair of guide rods or ways 12 and 13, u-pon which a reciprocatingtable 14 is mounted to slide in the usual way. A meat support 15 iscarried byv the table 14 and slides upon the table in a directiontransverse to the direction of reciprocation of the table. The usualclamp 16 is provided for holding the meatin place, and the4 support 15is fed transverselyof'the reciprocating table by a feed screw formedupon theshaft 17. The shaft 17 is given a slight rotary movement at`each reciprocation of the table 14 by means of a ratchet wheel 18actuated by a pawl 19 carried upon an arm 20, which is 1n turn operatedy a rack segment 21 on a lever L2. The lever 22 is oscillated by meansof a cam 28 journaled on the lower surface of Specication of LettersPatent.

the table 14 and oscillated by a link 24 which co`nnccts the cam 23 witha pivot Din 25 secured to a pitman rod bymeans of which the table 14 isreciprocated. A cam segment 27 maybe shifted by a rod 28 and a lever 29to regulate the amount of rotation of the ratchet wheel 18 for eachoperation ofthe pawl 19. The ratchet feed as described 'is shown andclaimed in our c0- pending application, Serial No. 222,802.

The pitmanrod 26 for reciprocatingthe table 14 is operated by a crank 30secured to an upright shaft' 31 which extends through a bearing 32projecting downwardly from the upper plate of the base frame 10, asshown best in Fig. 5. Secured to the lower end of the shaft 31 is a'gear 33 which meshes with pinions 34, 35 and 36, as shown in Fig. 2.The pinion 34 isl connected with a. shaft journaled in a bearing 37 andarranged to drive the slicing knife 38 through a sprocket chain 39 inthe usual manner. The pinion is connected with a shaft- 40 journaled inbearings 41 and 42 and carrying a f1 wheel 43 which may be provided witha detachable handle 44 by means of which the machine may be drivenby'hand. when desired. The pinion 36 is connected with a. shaft 45, asshown in Fig. 6, the shaft being journaled in a bearing 46 formed on aplate 47 secured to thc outer face of the base frame so that the bearing46 projects through an opening 48 in the wall of the base frame.

A spur gear 49 is rigidly secured to the outer end of the shaft andmeshes with a pinion 50 journaled on a stud shaft 51 rigidly carried bya boss 52 formed on the plate 47. The pinion 50 is secured to one' endof a sleeve 53 which is journaled upon the stud shaft 51 and-whichcarries at its outer end a 4pulley 54 held in place by a cotter pin 55.The gears49 and 50 are inclosed in a casing 56 provided with an opening57 through which the shaft 51 extends to carry the pulley 54 outside ofthe casing. A circular plate 58 is secured to the outer end of thecasing 56 and forms a cover plate for the inner face of the pulley 54. Abelt 59 passes around the pulley 54 and a guard 60 covers the belt 59.and pulley 54 and is held inplace by a number of lag screws 61. Thebelt 59 is driven by a pulley 62 secured to a shaft 63 of e' motor 641The motor 64 is inclosed in a cylindrical casing and is located within acircular opening in the base' frame 10 formed by Webs 65 projectingdownwardly from the upper plate of the base, frame, as shown in Figs. 2,5 and 46. The lmotor is held rigidly in posiy tion by a flexible strap 66 which passes beleasing the screws and drawing the motor forwardly fromitscircular seat.v A `casing 70 4incloses the outer portio of the motor61V andris provided with an opening .7l through which the -shaftl 63extends and which is large enough to permit 'of' the passage of 'thepulley 62so that the casing' 70 72. through a switch 74 and cables 75 tothe .may 'be removed without detaching the pul.- ley 62 from the motorshaft. The belt guard inclos'es the pulley 62 and a portion of i thebelt passing over the pulley. A socket 7 2 for an electrical connectlon7 3 is mountedv upon the outer face of the casing 70, and electricalconnection is made from the socket It should also be noted that theratchet mechanism for feeding the meat support l5 is allinounted uponthe reciprocating table l14 and has no connection with the base frame10. This arrangement leaves the side of the rframe opposite the rotaryknife 38 free to support .the power drive. With ratchet drivespreviously in use this has been impos- .sible for the reason that someform of stop l mechanism supported upon the side of the base frame hasbeen necessary for the operation of the ratchet feed.
